Can windshield wipers cause a car alarm to go nuts?
I recently purchased a 2007 Toyota Sienna, and last night, after parking the van around 10PM, the alarm decided to sound off at approximately 4AM. Naturally, I assumed it was a break-in, so I checked outside and no one was around, so I turned off the noise and reactivated the alarm. Soon thereafter, the alarm began to ‘chirp’ intermittently and within 30-40 minutes, the alarm went off again! I even deactivated the alarm at one point, but it reactivated itself 30 seconds later! This became a cycle right up until 7:30 this morning when my wife took the van to work. I lost sleep, my neighbors were upset, and I didn’t know what to think. The one thing, however, that we concluded, was the fact that when I had turned off the ignition, the windshield wipers were not completely down, nor were they turned off. I have since contacted Toyota, and was told that the wipers most likely were the cause, but without looking at the alarm, they couldn’t be 100% sure. Any thoughts … car experts?
